About Jasmin Hofstetter

Dr. Jasmin Hofstetter is studying the kinetics of metallic impurities and dislocations in silicon, and their interaction during solar cell processing. She received a degree in physics from Freie Universität Berlin in Germany in 2006 and she completed a PhD in Photovoltaic Solar Energy at Universidad Politécnica de Madrid in Spain. She joined the PV group in July 2011 as a Humboldt fellow.
